BROADCAST

This invention relates to the method of building parallel data transmission through various channels and a system for parallel data transmission through various channels.

The methods of TV reception is changing with new technologies becoming available, and this circumstance causes that the recipients of TV transmission expect a parallel transmission of data, which usually is available through additional channels. Currently, parallel transmission can be realized, inter alia, through tablets and Smartphones.

The description of the international patent application number WO2013040533 A1 discloses a method for detecting and dynamic synchronizing of the content transmitted by interactive digital media platforms, thanks to which the viewer - when receiving information from the first device, obtains enriched information on the second device. As a result, the viewers can broaden their experience and knowledge. The basic information transmitted by the first device is detected by a sound signal, which is received and processed by the second device using an appropriate authentication key.

The description of the international patent application number WO/20 3/098660 discloses a system for detecting content through other device, originally contained in the first (major) device. It is equipped with a service platform adapted to communicate with a second device. The system is designed to provide information about advertising campaigns and commercial events. In this system logging is possible through the authentication system that uses a sound signal.

In turn, the international patent application No. US20140282677 A1 relates to a method for displaying on a Smartphone screen an enlarged secondary content in relation to the program displayed on the screen of the first device. The system operates via signals transmitted over the Internet, to which both devices must be connected.

Known from the Polish patent specification of the invention No. 181135 is the modulation method to transmit data signals, wherein by means of data signals the first carrier is modulated by a quadrature method with two sidebands. The essence of the solution is that from a modulated signal a signal with a single sideband with residual carrier wave is derived, which is then processed into long-wave range by mixing with the frequency of the oscillator and so processed signal is emitted.

The aim of the invention is to expand the possibilities of using data transmission in TV and radio broadcasts.
